Printed color is a mixture of cyan, magenta, and yellow, which are normally called the CMY color model.
When mixed in equal proportions the CMY color model produces black.
Note
CMY is also called subtractive or reflective color. The printer uses CMY toner plus K (black) toner
(CMYK color model) to provide full color printing.
The colors of the RGB color model can be mixed to produce the cyan, magenta, and yellow of the CMY
color model and vice versa. Two colors of one model are mixed to produce the color of the other model
(mixing blue and green produces cyan, for example). The remaining color is the complement of the col-
or produced (red in this example). Complementary colors are: red and cyan, green and magenta, blue
and yellow.
